MACHINE. FOR APPLYING FASTENING- STRIPS TO BOXES.

SPECIFICATION forming part of Letters Patent No. 406,736, dated July 9, 1889. Application filed January 26, 1888. Serial No. 262,005 (No model.)

To all whom it may concern:

Be it known that I, GUSTAV L. J AEGER, a citizen of the United States, residing at New ,York, in the county and State of New York,

have invented new and useful Improvements in Machines for Applying Fastening-Strips to Boxes, of which the following is a specificaing made to the accompanying drawings, in

which- Figure 1 represents a sectional front elevation of a machine embodying my invention. Fig. 2 is a vertical section thereof in the plane 00, Fig. 1. Fig. 3 is a sectional side elevation. Fig. l is a similar view of a 'portion of the machine, showing the folding device in a position differing from that shown in Fig. 3. Fig. 5 is a horizontal section in the plane y 11 Fig. 1. Fig. 6 is a sectional elevation of the box support and die, showing the same in the receiving positions, said figures being drawn to a larger scale than the preceding figures. Fig.7 is a similar view showing the die down upon the box. Fig. 8 is a vertical section in the plane ,2 a, Fig. 6. Fig. 9 is a vertical section in the plane :20 m, Fig. 7. Fig. 10 is a perspective view of a box having the fastening-strips applied. Fig. 11 is a face view of a portion of astrip. Fig. 12 is an elevationof the die, showing means for heating the same. Fig. 13 is a plan view similar to Fig. 5, but without any parts being cut away. Fig. 1a is a sectional side View of a trough and a corrugated table. Fig. 14* is a transverse sectional view of Fig. 14.- Fig. 15 is a side elevation of a machine.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates a frame suit-ably constructed to support the operating parts of the machine. B is the box-support, which is provided with a shank a for securing it to the frame. of the box-support diverge and form an angle of ninety degrees with each other, so that the corner of the box \V, which is placed upon the same, will receive a proper support.

The faces I) b' The die 0 is located directly above the boxsupportB, and is provided with diverging cheeks c 0, corresponding to those of the boxsupport. The die is movable toward and from the box-support, its shank 0 being guidedin vertical ways formed ina portion of the frame. of any suitable mechanism-such, for instance, as that here shown, Figs. 2, 3, and 15-which consists of foot-lever D, having thereon a cam-surface (1, upon which rides a roller-stud (1, carried by a lever E, which is in engagement at c with the shank of the die. The foot-lever D may be of any suitable construction, as seen in Fig. 15.

The fastening-strip S has a width corresponding to the depth of the box, and is'fed directly between the die and the box-support that is to say, over the corner of the interposed box IV and in a direction perpendicular to the depth of the box-support. In the example shown in the drawings, Figs. 1, 2, 5, 13, and 15, the fastening-strip is drawn from a roll S by a feed-roll F,'which rotates in contact wit-h a moistening-roll G, located within a fount G, the shafts of both rolls F and G having bearings in suitable boxes on the fount G.

In practice I make use of astrip S, which has been previously provided with a dry coating of mucilage or. other suitable adhesive, which is moistened to render thestrip adhesive by the moistening-roll G, the fount G being supplied with water. To guide the strip between the roll S and the feed-roll, I provide suitable guides g g, which are laterally adjustable upon supports g' g to adapt them to any particular width of strip. Set- It can be actuated by the use screws g g are provided to fix the guides adhere to the table. A bar f, extending 7 respond therewith, Figs. 2, 5, 6, and 7 above and across the table f, prevents the l is arrested by a stop j, Figs. 6 and '7, which strip from rising. The table f is shown in Figs. 5, 13, 14, and 14" as having corrugations or ridges. 7

The feed-roll F is intermittently rotated by any suitable connection with a moving part of the machine. In the example shown in the drawings, Figs. 1 and 2, I make use of the following means: On the shaft of the feedroll is rigidly secured a ratchet-wheel 7z,which is engaged by apawl h, pivoted to an arm 7L2, loosely pivoted on the feed-roll shaft. The arm 71 is connected by a link 71 with a lever II, pivoted to the frame. brated in one direction by a cam I-I, secured to the shank of the die 0, and a spring h moves it in the opposite direction.

It will be noticed that when the die C descends the lever H is swung outward and the feed-roll F is turned in the direction of the arrow marked near it in Fig. 1 to feed the strip forward over the corner of the box. On the reverse movement of the die the pawl h passes over the teeth of the ratchet-wheel and the feed-roll remains stationary. The shaft of the moistening-roll G is connected with the shaft of the feed-roll F by suitable gears, Fig. 2.

To sever the strip S into suitable lengths I make use of a cutter I. This cutter can be of any suitable construction and operation. In the example shown in the drawings, Figs. 1, 2, 6, and 7, I have formed the same integral with and directly on one side of the die. It could, however, be made separate from the die and secured thereto. This cutter I severs the strip S into suitable lengths in co-operation with a blade I, which is secured to the fount G, and is made adjustable by the set-screws 2', Figs. 1, 2, 14, and 15. Its upper edge extends parallel to the cutter.

In order that the strip may not be torn or distorted by the cutter, I serrate or flute the surface of the latter at the lower portion thereof or throughout its entire dept-h, and serrate or flute the edge of the blade I to corserrations also improve the appearance of the fastening-strip. (See Figs. 10 and 11.)

It will. be noticed that the strip S is supported on one side upon the blade I while being severed; but in order to support it on the opposite side and also to hold the severed length firmly and truly upon the box I make use "of a suitable yielding clamp J, which is fitted in the die 0, and engages with the strip slightly in advance of the cutter I and holds it firmly to the box.

This lever is vi These may be a screw engaging a longitudinal slotin the clamp. In the outer end of the clamp is formed a groove, the sides of which correspond in inclination to the inclination of the sides of the box. As the die descends one or more of the clamps, as the case may be, engages with the strip S and holds it firmly to the corner of the interposed box while the cutter I is in action. During the movement of the die 0, subsequent to the engagement of the strip S by the clamp J, the clamp yields until its outer end lies flush with the faces 0 c of the die 0. In this position itsinner end engages with the end of the recess j, and the clamp consequently forms an unyielding and operative portion of the die when the said die is in engagement with the strip, Figs. 7 and 0. It is evident that a single clamp J, extending across the depth of the die, could be used in place of the several clamps shown.

In many instances it is desirable to turn over and lay one end of the fastening-strip S in the interior of the box,as shown in Fig. 10. To adapt the machine for this purpose also I provide a folding device which can be brought into use when so desired, and the fasteningstrip, fed by the feed-roll, is wide enough to permit-a portion of the same to overlap the top of the box.

Referring to Figs. 3, 4, 5, 8, and 9, the boxsupport B is slotted or provided with a central longitudinal recess is, to permit the introduction of a horizontally-movable slide K, on the inner end of which is a supporting-segment L, which is pivoted to the slide and is engaged by a spiral spring I, coiled in a longitudinal recess in the slide. The spring tends to turn the supporting-segment about its pivot, and, if desired, a suitable follower may be placed between thespring and supporting-segment. The top of the supportingsegment is roof-shaped to correspond to the support B. When the slide is in its forward position, the supporting-segment abuts against the end of the recess 7;, Figs. 3 and 8, and forms a support for the portion of the box above the same, whereby the continuity of the box-support is preserved; but when said slide is withdrawn, Figs. 4 and 9,the springl turns the supporting-segment about its pivot, and a portion of the box-corners is left unsupported.

The folder Mis located above the slide K, and is provided with inclined faces corresponding to those of the box-support B. It engages with the portion of the strip which overhangs the top of the box and bends or turns it downward, and then by a forward or translatory movement lays it upon the interior of the box. During the forward movement of the folder the slide K withdraws and the supporting segment turns about its pivot, thereby making room for the passage of the folder beneath the top corner of the box. In this manner the box-corner is supported throughout its depth while under the action of the die, while subsequently a portion of the same is free for the turning over of the fastening-strip.

Any suitable means can be employed for actuating the folder and slide. In the example shown in the drawings, Figs. 3, 5, and 13, the slide K is guided in asuitable box 0, and its rear end is engaged by one end of a lever N, Figs. 3, 13, and 15, which is pivoted at n to the frame A of the machine, and carries on its free end a roller-stud N, which rides upon a cam-face (1*, formed on the foot-lever D. On inspection of this cam-surface and that for actuating the die it will be seen that the lever N is not actuated to Withdraw the slide K until. the downward movement of the punch is completed, after which the punch remains stationary and the slide is withdrawn. The folder M is in the form of an arm or lever, and its rear end is connected by alink m with a lever P, pivoted at p to the box 0. A pin 1) on the slide K engages the free end of the lever P as the slide is withdrawn, and moves the folder M forward. The folder is connected at or near its central portion with the slide K bya pin m and slot 0,

connection which steadies the folder. A slot 0-, intersecting the slot 0, allows the folder to reach its elevated position, Fig. 3, in which it normally is retained by a spring Q, which is connected at one end to the lever P and at the other end to a standard on the box 0. The descending die 0 engages with and vibrates the folder M, forcing it downward upon the overlapping portion of the fastening-strip, whereupon it is moved forward, as best seen in Fig. 9, to fold in the said overlapping end. It will be noticed that the extreme free end of the folder is recessed to permit the same to pass into thebox. It not being desirable that the clamps J should engage the folder, such of the same as would engage with the same on the downward stroke of the die can be raised flush with the punch, as shown in Fig. 8, and fixed in this position by means of screws j, Figs. 6 and 7.

A gage R, which is adjustable by means of a slot and screw connection with the frame A of the machine, Figs. 1, 2, '5, 13, and 15, is used, so that the box can be readily placed in the correct position on the support. This gage is in the form of a plate, Fig. 1, and serves also to steady the box.

' The gage-plate R is to be fixed in a stationary position after being adjusted to the correct position to serve as an abutment for the edges of the box on the angular support. For such purpose the connection of the gage-plate with the main frame is through the medium of the horizontal arm having a longitudinal slot through which the fastening-screws pass into the main frame, as clearly shown in Fig. 5.

A presser-plate 25, secured to the blade I or to the fount- G, Figs. 1, 14, and 14*, holds the box firmly against the support.

With boxes of diiferent depths it is obvious that the folding mechanism must be set accordingly, and in view of this'I have made the same adjustable.

Referring to Figs. 3, 4, and 5, it will be seen that the box 0 is adjustable horizontally by means of a bolt q and slot q connection with the frame A. For a deep box the box 0 is moved backward until the folder comes into the correct position toengage with the overlapping end of the fastening-strip. .The slide K is moved back correspondingly, and the dog K thereon, which is engaged by the lever N, is set to remain in engagement with the said lever. The space of the recess k, Figs. 3, 4, 5, 8, and 9, remaining between the segment 'L and the end of the recess is filled out by fillingblocks L, which fit the recess and have roofshaped tops to correspond with the box-support, whereby the continuity of the support is preserved.

If the fastening-strip is coated on one side with colophonium or similar adhesive which can be softened by heat, the punch is heated by any suitable means. In Fig. 12 I have shown perforated gas-pipes TT on both sides of the punch for directing a number of jets on the said punch.
